Derivative seismic processing method for GPR data

Ground-penetrating radar (GPR) is a newly developed geophysics method. It belongs to one of the electromagnetic methods. In a broad sense, it is also a remote sensing technique, but the processing method for GPR data is quite different with the one for remote sensing data. The processing method is the key to develop the technique, so it is an urgent task to develop GPR processing methods at the current time. Based on the close similarity between ground-penetrating radar and the reflection seismic method, this paper presents the derivative seismic processing methods for GPR data, including the CMP processing method, two dimensional filtering, migration and simulation techniques. The principle and an algorithm are given. The derivative seismic processing methods are shown to be very effective for GPR data. GPR is a very convenient, rapid, precise way to get underground information.
